2 Claims. (Cl. 101-3) Another object aims at trimming the board in stages so as to obtain clean severing cuts.

18 A still further object aims at means for providing grooves in composition boards to enable their assembly in lap-joint arrangement.

Another object aims at providing grooves by a series of forming rollers.

2o It is also an object to provide certain features of construction and arrangement tending to enhance the utility and efliciency of a machine of the character described.

With these and other equally important ob- 25 jects in view, which will become apparent from a perusal of the invention, the latter comprises the means described in the following specification, particularly pointed out in the claims forming a part thereof, and illustrated in the accompanying 30 drawings, in which:

Figs. 1 and 3 are continuations of each other and illustrate a sectional elevation of the apparatus constructed in accordance with my invention.

5 Figs. 2 and 4 respectively, are plan views of the construction shown in Figs. 1 and 3.

Fig. 5 is a section on the line 5-5 of Fig; 3.

Fig. 6 is a section on the line 6-6 ofFig. 8. Flg. 7 is a section on the line 'l.---! 0! Fig. 2.

40 Fig. 81s a section on the line 8-8 of Fig. 7.

Fig.9 is a sectionpn the line 9-9 of Fig. 4.

Fig. 10 is a fragmentary plan view of a modification.

Fig. 11 is a section on the line i I--i I of Fig. 10.

45 Fig. 12 is a section on the line l2-|2 of Fig.

10, and

Fig. 13 is a. cross section through a finished board.

In carrying out my invention, the composition 59. board is to be embossed or provided with textureon its surface, thereafter to be provided witha groove along its edges'and trimmed to the required size.

As indicated in Fig. 1, the composition boards Ii, when-produced, are piled on a truck II and supported by metal plates l2, so that in alternate arrangement, the composition board rests on the lowermost metal plate and is below the vertically adjacent metal plate on which again a board rests, and so on until the truck is loaded and 5 brought adjacent to an intermittently operated endless conveyer, generally designated by it, which comprises a pair of chains 15, It, trained round gears ill and i3, and borne by a plurality of small rolls l9 to provide an upper horizontal m run 2E3. I The lower run 25 of the intermittent 'conveyeru is trained around idler gears 22 and acliusting means 23 .are provided tomaintain the-belt in taut relation. 15

An attendant places the metal. plates it, each carrying a composition board it, successively onto the conveyer M which are brought to a hydraulic press generally designated by 26. The plate it, with its superposed board it being placed above as the piston 25, the latter is forced upwardly against an embossing plate 26, (Figs. 1, 7 and 8), mounted to acarrier plate 21 reciprocatingly fitted between guide beams 23, 28 and connected to the piston rod 30 of an air cylinder 38. portion of the embossing plate 28, superposed to the piston 25, becomes smudgy or covered with foreign substances, then .the air cylinder 38 is actuated to cause the plate to move toward the left, as viewed in Fig. 1 until the clean portion of so the plate 26 is in alignment with the piston 25.

At each side of the pressis anoil pan 32 from which oil is delivered unto rotary. brushes 33,. adapted to clean the smudged surfaces of the plate 26. After the clean plate portion has been as in use for some time, and has become unsuitable, then it is moved to the extreme right position as viewed in Fig. 1, and the unsuitable portion is then cleaned by the rotary brushes at the right of the press 24. e 49 It is, of course, understood that the invention is not predicated on the particular type. oi press employed, nor on the particular means for cleaning the embossing plate to prevent interruption of the continuous process of pressing and otheris wise treating the composition board. I j 'The particular, driving means for efi'ectuating intermittent motion otthe conveyor i4 is not I illustrated as not aflecting the invention, as any means suitable or preferred may be employed. so The raising of the conveyer by the piston oi the press '24 is possible by reason of the adjusting or compensating means 23, aswill be readily understood by those versed in the art.

Adjacent to the conveyor I4 is another 0011- If the 25 veyer .(Figs. 3 and 4) generally designated by 34, which is continuously actuated and trained around gears 35, 36, and 31. The upper horiand is provided preparatory to execute a severing cut as will be hereinafter described.

The conveyer 34 leads to a third conveyer, generallydesignated by 43, which is trained around the gears 44, 45, and 46.

The upper run 41 is level with the upper run 38 of conveyer 34 and supported by a plurality of rolls 48. In traveling, the conveyer 43 forces the metal plate I2 and the composition board Ill between three sets of rollers for pressing or forming the grooves on the board l (Fig. 13), whereby the same may be arranged in lap joint formation.

Of the pair of rollers 49, 49a, the roller 49 is a form roller which imparts to the board III a slight groove at the'edges and at'the center. The next roller pair 50, 50a, and the third roller pair. 5| 0 contribute to produce the grooves of desired dimensions.

" not formed by merely utilizing forming rollers.

After passing the rollers 6 I 6la, circular knives 52, 53 and 54 mounted on a transverse shaft- 55 engage the board I0 for the purpose of trimming off the edges of the board and completingthe severing cut at the center of the hoardinitiated by the knife 4|.

Accordingly, at the discharge end of the conveyer, each plate l2 carries two boards and the plates are conducted by a discharge apron 56 onto a truck 51 The boards l0 are provided with grooves or rabbets 58, whereby they may be arranged in interfitting relation so that they may be used as a surface covering of uniform thickness throughout.

In the event the boards. are not produced by a semi-dry process, but are exceedingly hard, the

formation of grooves is carried out in a slightly modified manner.

- As indicated in Figs. to 12, the-grooves are which produce the grooves by pressure, butshavings are cut away so as to relieve the necessity of high pressure for extremely hard material.

Between the pairs of rollers 49, 49a and 50, 60a,

there are interposed pairs of circular knives to cut away a strip at-the longitudinal edges of the board.

At one edge are a pairof circular knives 59, 60 at right angles to one another and adapted to cut away a rectangular strip; likewise knives 6| and 62 cut away a strip at the other edge. The strips are discharged by angle irons 63 into receptacles 64.

The knives 60, 62 aremounted on a horizontal shaft 65, while the knives 59, 6| are securedto the upper end of vertical shafts 66, 61, which 'are geared to a' horizontal shaft 68.

Attention is called to the fact that the plates l2, when arranged on the conveyers, are held in' place by fingers 69 (Fig. 9). 7

While the drawings show preferred embodiments of the invention, numerous changes and alterations may be made without departing from the spirit of the invention.

I, therefore, do not limit myself to the details "of construction and arrangement, as shown, but

wish to include all departures falling within the scope of the invention as defined in the appended claims.

I claim:

. 1. Apparatus for treating composition boards,

including an intermittently moving conveyer on Y which the boards are placed, 'a press having an embossing plate for imparting texture to the boards while on said conveyer, and means for rapidly shifting said plate to present a clean surface to the board.

2. Apparatus for treating composition boards,- including anintermittently moving conveyer on which the boards are placed, a press'having' an embossing plate for imparting texture to the boards while on said conveyer,,means for rapidly shifting said plate to present' a clean surface to the board, and means for cleaning the used portion of said plate during the operation of said press.
